GTX275 vs HD4890 showdown: from a single card to 3-way SLI/Tri-Fire

Can't go through all of it now but I will bring up one question.

Why are they using 3 differant 4890's and all Gainward 275's? I'm not questioning their results but from a testing point of view it seems a bit odd to me.
 
Did not take much from that review guy seems like a noob reviewer. His tables were also of the worst colours i have ever seen to try and understand what i was looking at. Tri-crossfire was a sweet spot in the 3 series if this guys review is to be believed then its not any more as it does not seem to work in most of the games.
 
4890 crossfire is faster then 4890 trifire , sometimes faster then tri 275 sli.

i guess it just shows trifire and 3sli is not worth it.

colors of graphs dont help ;/

Its shows that something aint right with the drivers yet for the 4890 & rightly so because its new & other tri fire review of older ATI cards show that the gains are real.

And i can assure you that tri better because its the minimum that will power my 30" with some games.

If your comment was the case then the words that TriFire is the sweet spot would on never come into being.

You just gotta look at the start and end blends for the colors on the graphs - but its not exactly very reader friendly :(

Granted 2560x is a bit higher than 2048x but a couple of decently clocked 260GTX powers everything fine with overkill framerates with maxed settings for me - so I'd have thought a couple of 275 with reasonable overclocks should handle that kinda res just fine.

The 275 looks sweet & would be my choice of multi GPU NV cards.

Remember im on 3870's
 
Only game that makes my 260GTX SLI cry at 2048x with all settings maxed is uh Crysis - IIRC 45min 56avg 67max. But I would never build a PC or judge a PC around its performance in Crysis.

In mirrors edge for instance I never drop under 60 and avg ~90-100fps.

2048x1152 or 2048x1536?

I ask because there is a huge difference in pixel count between the two.

2048*1152=2,359,296
2048*1536=3,145,728
2560*1600=4,096,000

Still nearly an extra million pixels on a 30" over the 4:3 res. (more than a 720p image!)
 
I just tested 2560x1600 on my projector (only display I have that can even display that resolution - my TFTs just blank don't even scale it) and theres quite a drop off from my 2048x performance :P but 2x 260GTX SLI is still giving perfectly playable fps. (At a rough guess - I haven't done the maths, framerate is about 40% lower).
